reversed flow

i am trying to solve free surface flow past a cylinder such that cylinder is half in water half in air. The b.c's that i am giving are velocity inlet at water inlet, mass flow outlet at water outlet and pressure inlet (all pressures as 0)at top as specified in the exaple of VOF flow in the fluent guide in which they have solved a swirl 2phase flow. I am using geoconstruct.

My problem is that i always get reversed flow if i use pressure inlet condition. I have tried changing the flow domain ie increased the area but that does not help. Can someone tell me what to do.

If someone has solved similar problem please help. thanks, vineet

Re: reversed flow
you may try to use velocity inlet for water and air inlet and outflow at outlet.

Re: reversed flow
This was the conditions that i was using already. still getting reversed flow.
